A Florida woman who traveled to Costa Rica to celebrate her birthday has vanished, her family said.

Carla Stefaniak, 36, of Hallandale Beach, had traveled to the country with her sister-in-law, April Burton, last week, but Burton left one day before her, she told CBS Miami. Stefaniak never made her flight the next day.

Burton told the station she last heard from Stefaniak at 8 p.m. on Tuesday, who messaged her to say the power had gone out because it was raining heavily. She added in the message, “It’s pretty sketchy here.”

She also reportedly FaceTimed a friend, saying she was thirsty and was going to ask the security guards at the Airbnb to buy her a bottle of water.

She hasn’t been heard from since, her family said.

The family told the station they've contacted the owners of the Airbnb, an Uber driver Stefaniak had ridden with and the security guards at the Airbnb, who all said Stefaniak got into an unknown car early Wednesday morning with her luggage.
